xia2 & Latest XDS

The current version of xia2 (0.2.6.4) will not work with the latest version of XDS. This was OK, except the previous versions of XDS expired today, so as of right now running with the -3d option won't work. I think I have fixed this so that it should work fine with the new version (June 2, 2008) and I am running final tests now. Should be able to bundle a release tomorrow.
